Abstract: Thermosetting polymers and the electrical laminates made therefrom are disclosed. The polymer comprises the cross-linked product of: a) one or more ethylenically unsaturated aromatic monomers, optionally containing a halogenated monomer to impart fire retardation, and b) a vinyl-terminated polybutadiene or butadiene-styrene copolymer containing either a urethane or an ester group. It has been discovered that an unexpected combination of thermal, electrical, and mechanical properties are obtained from the composition recited herein. The composition is ideally suited as a matrix polymer for electrical substrate applications.

Abstract: Thermosetting polymers and the electrical laminates made therefrom are disclosed. The laminate comprises a cross-linked product of: a) one or more ethylenically unsaturated aromatic monomers, with fire retardation being optionally contributed by one halogenated monomer, b) a vinyl-terminated polybutadiene or butadiene-styrene copolymer containing either a urethane or an ester group, and c) a chemically modified polyphenylene ether resin, preferably low molecular weight chemically modified polyphenylene ether resin. It has been discovered that an unexpected combination of thermal, electrical, and mechanical properties are obtained from the composition recited herein. Therefore, the composition is ideally suited as a matrix polymer for electrical substrate applications.

Abstract: The invention relates to a product and process for producing molded unsaturated polyester products. An unsaturated polyester is formulated with two initiators in combination with two reagents which scavenge free radicals; one of the scavengers traps free radicals which occur at low temperatures of 20 to 50° C.; whereas the second scavenger traps free radical which are produced and occur in the compositions at temperatures above those low temperatures. The compositions of the invention eliminate premature gelling and insure shelf life.
